IMPROVEMENT IN GRAIN-SEPARATING ATTACHMENTS TO THRASHING-MACHINES.

Specification forming part of Letters Patent No 123,188, dated January 30, 1872.

Speciiication describing a certain Improved Cleaner Attachment to Thrashing-Machines, invented by ZEPHANIAH MILLER, of Canal Fulton, in the county ot' Stark and State of Ohio.

My invention consists of a tailing screenconveyer and elevator, combined with the sieves and with the straw-carrier, by which the pods and tailings are sepa-rated from the stems and other large refuse-matter that is carried over and conveyed back to the bottom of the returning part of the straw and chaff-carrier, to be returned to the thrashing-cylinder for being more completely thrashed. It also consists of a conveyer-elevator and another conveyer arranged to receive and convey the dirty seed which drops down through a slot in the said box back upon the sieve again to be subjected to a second operation.

Figure lis a longitudinal elevation ot' my improved cleaner attachment, the section being taken on the line as x of Fig. l. Fig. 2 is an end elevation with some parts sectioned. Fig. 3 is a transverse section taken on the line y y of Fig. l; and Fig. 4 is a section on linez z.

I propose to apply a coarse sieve or screen, A, at the lower end of the top screen B, and under it a conveyer, O, Wit-l1 an elevator, D, at one end, with which elevator is another conveyer, E, at the upper end of said elevator, all being arranged to take the pods, tailings, and all other of the coarsest matter likely to coutain good grain not sufficiently thrashed, and separate them from the stems and other refuse carried over, and convey them back to the closed bottom F ofthe strawcarrier G, to be conveyed back by the returning side of said strawcarrier to the thrashingcylinder, to be acted on again by it and more thoroughly thrashed than before, and thus save considerable good grain otherwise lost with the refuse. This screen is so connected at the end of the screen B as to form a continuation of it, and is arranged on an ascending incline that may be shifted to a greater or lesser amount by adjusting the outer edge up or down, for which a series of holes, H, is provided `in the sieveholding frame for the rod I, by which the said screen A is held. Below said screen are chutes K for conducting the droppings into the conveyer C. The said screen is detachably connected to the screen B, so that it may be readily removed for cleaning or when not required for use. I also propose to arrange a conveyer, L, under the slot M in the bottom end where the seedbox is arranged to receive the seed and grain fallin g through said slot and deliver it to the elevator O, by which it is carried up to the conveyer P, which discharges it upon the upper end of a screen, B, to be screened again for saving some ofthe grain irst discharged with the seed. I also propose to suspend the screen-frame by rods Q and connect it to the crankshaft R by spring-bars Sin such manner that the said rods a-re maintained at such an inclination from the vertical line that the horizontal motion in one direction imparted by the crank elevates the sieves while the other horizontal motion depresses them so that a combined horizontal and vertical motion is imparted to the sieves, which is calculated to have a better eifect in separating the grain from the refuse than horizontal movements only.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the conveyer L, elevator O, and conveyer P with the slotted bottom board N and the sieve B, all substantially as specified.

2. The subject-matter of first claim, in combination with sieve A, conveyers G E, elevator D, and carrier G, as and for the purpose set forth. ZEPHANIAH MILLER.
